libata depends on scsi_host_template for module reference counting and
sht's should be owned by each low level driver. During libahci split,
the sht was left with libahci.ko leaving the actual low level drivers
not reference counted. This made ahci and ahci_platform always
unloadable even while they're being actively used.
Fix it by defining AHCI_SHT() macro in ahci.h and defining a sht for
each low level ahci driver.
stable: only applicable to 2.6.35.

The PKT_CTRL_CMD_STATUS device ioctl retrieves a pointer to a
pktcdvd_device from the global pkt_devs array. The index into this
array is provided directly by the user and is a signed integer, so the
comparison to ensure that it falls within the bounds of this array will
fail when provided with a negative index.
This can be used to read arbitrary kernel memory or cause a crash due to
an invalid pointer dereference. This can be exploited by users with
permission to open /dev/pktcdvd/control (on many distributions, this is
readable by group "cdrom").

The HW by default has RX coalescing on. For iWARP connections, this
causes a 100ms delay in connection establishement due to the ingress
MPA Start message being stalled in HW. So explicitly turn RX
coalescing off when setting up iWARP connections.
This was causing very bad performance for NP64 gather operations using
Open MPI, due to the way it sets up connections on larger jobs.

f4347553b30ec66530bfe63c84530afea3803396 removed the edac polling
mechanism in favor of using a notifier chain for conveying MCE
information to edac. However, the module removal path didn't test
whether the driver had setup the polling function workqueue at all and
the rmmod process was hanging in the kernel at try_to_del_timer_sync()
in the cancel_delayed_work() path, trying to cancel an uninitialized
work struct.
Fix that by adding a balancing check to the workqueue removal path.

Just like pkgtemp registers another core of the same package when one
gets removed, coretemp should register another hyperthread (if
available) in that situation.
As pointed out in the patch fixing the respective code in pkgtemp, the
list protectng mutex must be dropped before calling
coretemp_device_add(), and due to the restructured loop (including an
explicit return) the "safe" variant of the list iterator isn't needed
anymore.

pkgtemp_device_remove(), holding the list protecting mutex, calls
pkgtemp_device_add(), which itself wants to acquire the same mutex.
Holding the mutex over the entire loop body in pkgtemp_device_remove()
isn't really necessary, as long as the loop gets exited after
processing the matched CPU.
Once exiting the loop after removing an eventual match, there's no
need for using the "safe" list iterator anymore.

In commit 0dca94baeab4a1a514841b0a4c8e3a51dfb4d5ae the call to
platform_driver_unregister() was made conditional upon !HOTPLUG_CPU,
but the return value from coretemp_init() was left to indicate an
error. This isn't correct, as the negative return value indicates to
the module loader that initialization failed, which isn't intended
here and results in dangling pointers.

This patch fixes the issue which was observed while transfering
a large file ( > 20MB) over USB (OMAP MUSB controller acts as USB host)
to an attached USB thumb drive.
It was found that CDB field of CBW packet was set to 0x0. This was
due to missing a barrier before DMA engine starts transfer.
This buffer is allocated using dma_alloc_coherent which gives
non-cacheble but bufferable memory and hence needed a write
memory barrier to flush the write buffer.

This patch fixes one bugs of OUT transfer in double buffer case:
-the current code only enable autoclear for dma mode 1, and not
for dma mode 0
Without this patch, test #5 of usbtest can't be passed if we
configure musb as g_zero and use fifo mode 3 to enable double
buffer mode.
With this patch and the following patch(fix dma length),
on my beagle B5, test#5(queued bulk out) may go beyond
18Mbyte/s(seems dma mode 0 is quicker in double buffer case)
if musb is configured as g_zero and fifo mode 3 is taken, follows
the test command:
#./testusb -D DEV_NAME -c 1024 -t 5 -s 32768 -g 8 [1]
Also I have tested this patch can't make g_ether broken.

This patch fixes one infinite hang of bulk IN transfer in double buffer
case, the hang can be observed easily by test #6 of usbtest if musb is
configured as g_zero and fifo mode 3 is taken to enable double fifo.
In fact, the patch only removes the check for non-empty fifo before
loading data from new request into fifo since the check is not correct:
-in double buffer case, fifo may accommodate more than one packet,
even though it has contained one packet already and is non-empty
-since last DMA is completed before calling musb_g_tx, it is sure
that fifo may accommodate at least one packet
Without applying the patch, new requst enqueued from .complte may not
have a chance to be loaded into fifo, then will never be completed and
cause infinite hangs.
With the patch, on my beagle B5, test#6(queued bulk in) can be passed and
test result may go beyond 33Mbyte/s if musb is configured as g_zero and
fifo mode 3 is taken, follows the test command:
#testusb -D DEV_NAME -c 1024 -t 6 -s 32768 -g 8 [1]

For shared fifo hw endpoint(with FIFO_TXRX style), only ep_in
field of musb_hw_ep is intialized in musb_g_init_endpoints, and
ep_out is not initialized, but musb_g_rx and rxstate may access
ep_out field of musb_hw_ep by the method below:
musb_ep = &musb->endpoints[epnum].ep_out
which can cause the kernel panic[1] below, this patch fixes the issue
by getting 'musb_ep' from '&musb->endpoints[epnum].ep_in' for shared fifo
endpoint.

Recent changes in the usbhid layer exposed a bug in usbcore. If
CONFIG_USB_DYNAMIC_MINORS is enabled then an interface may be assigned
a minor number of 0. However interfaces that aren't registered as USB
class devices also have their minor number set to 0, during
initialization. As a result usb_find_interface() may return the
wrong interface, leading to a crash.
This patch (as1418) fixes the problem by initializing every
interface's minor number to -1. It also cleans up the
usb_register_dev() function, which besides being somewhat awkwardly
written, does not unwind completely on all its error paths.

In order to support multiple ST platform devices, a new symbol
'st_get_plat_device' earlier needed to be exported by the arch/XX/brd-XX.c
file which intends to add the ST platform device.
On removing this dependency, now inside ST driver maintain the array of
ST platform devices that would be registered.
As of now let id=0, as and when we end up having such platforms
where mutliple ST devices can exist, id would come from
protocol drivers (BT, FM and GPS) as to on which platform device
they want to register to.
